Additional Details

The AB28F400B5B80 operates at 5V and offers fast read access times, typically in the range of 80ns. It supports sector erase, allowing individual sectors to be erased and reprogrammed without affecting other parts of the memory. The device also features erase suspend and resume capabilities, which enable the system to interrupt the erase operation to read data from other sectors and then resume the erase operation later. This enhances system responsiveness and efficiency. The AB28F400B5B80 is available in various packages, including PLCC and TSOP, to suit different application requirements. Its low power consumption makes it suitable for battery-powered devices and energy-efficient systems. The Flash memory is designed for high endurance, with a specified number of erase/write cycles. Proper handling and ESD protection are essential to ensure the device's long-term reliability. Data retention is typically specified for a long duration, ensuring that data is preserved even when power is removed.
